Firms selling junk food are exploiting regulatory loopholes to advertise products to millions of children online, experts warn.
Food companies are fuelling the obesity crisis by using increasingly sophisticated methods to influence youngsters on the internet, according to a report by the World Health Organisation.
In 2017 the Advertising Standards Authority banned junk food adverts from being shown when children make up 25 per cent or more of the audience. The rules encompass all types of media, but academics believe it is simple to get around them online because it is impossible to monitor who is viewing the content.
